Or HaChaim on Leviticus 26:31/אור החיים על ויקרא כ״ו:ל״א

1 ונתתי את עריכם חרבה, "and I will turn your cities into ruins." The Torah means that not only will our cities no longer be a model for other nations but that they will be inferior to the civilisation of the Gentile nations. This is a source of great distress. Isaiah had this in mind when he described the cities of Yehudah and Zion as being turned into a desert (Isaiah 64,9) unless the Jewish people would mend their ways.

2והשימותי את מקדשיכם, "and I will make your Sanctuaries desolate." This is a reference to symbols of impurity in the Temple. The forces of the קליפה are also known as שממון.

3ולא אדיח בריח ניחחכם. "and I will not savour the fragrance of your sweet odours." This means that G'd will not even be pleased by the good deeds of the Jewish peolpe at that time. Good deeds also qualify for the description ריח ניחח, sweet odour. Jeremiah made the same point in Lamentations 3, 5 שתם תפלתי, "He shut out my prayers."
